Abstract: The present invention provides methods of imaging dental tissue. More particularly, the invention relates to a method of imaging dental caries by administering a topical intra-oral composition that provides enhanced radiographic imaging.

Abstract: An imaging system and methods for processing a two-dimensional image from three-dimensional image information is disclosed. Images are segmented into foreground regions and background regions. An object-centered coordinate system is created and a hierarchical anatomical model is accessed to classify object in order to identify an anatomical object. The anatomical text labels are generated and positioned on the image slices and at least one image slice is displayed.

Abstract: A method and system is provided for charting tooth decay to assist in caries management. Specifically, the invention provides a computer system, a Graphical User Interface(GUI), a method, and associated computer code for presenting an interactive tooth chart comprising selectable, anatomically correct tooth icons corresponding to a dental patient's teeth. The invention allows a user to select regions of each individual tooth icon to record the condition of the selected region. According to the invention, a dental patient is selected from a patient data base, the patent's teeth are examined, and the condition of each tooth region is recorded using selectable icons. The invention further provides automatic characterization of dental conditions based on standard values and previously recorded conditions to indicate progression of disease. In an alternative embodiment, the invention provides a recommended course of clinical management based on the information recorded.

Abstract: A method for quantitatively evaluating the quality of radiographic films is disclosed. The method provides for digitizing a radiographic image to form a digital image made up of a plurality of pixels. The individual pixels of the digitized image are assigned grey level values. These grey level values are summed to form a global histogram representing all of the pixels of the digital image. The histogram is subsequently binned and subdivided to form first and second binned histograms. A series of rules is applied to these histograms to evaluate whether the radiographic film is clinically acceptable for use in making a diagnosis.
